Linear Ball Bearings

Minuteman Self Lubricating
Linear Bearings

 

  • Coefficient of Friction: .0015 - .015

  • Running Clearance: Zero Clearance

  • Operation: Noisy and produces resonance

  • Motion: Linear Only

  • Fails in applications which feature:
    contamination, washdown, shock, rapid oscillation, high loads

  • Shafting: RC60 Hardened Shafting ONLY

  • Magnetic

  • Misaligned Shafting: Works Well

  • Moment Loading: Works Well

  • Mechanical Failure Mode: Extreme - balls
    can fall out of the housing - shafting can
    become grooved

  • Chemical Resistance: Questionable


     

  • Coefficient of Friction: .09 - .15

  • Running Clearance: + .001

  • Operation: Quiet & Smooth

  • Motion: Linear & Rotary

  • Thrives in applications which feature:
    contamination, washdown, shock, rapid oscillation, high loads

  • Shafting: Hardened & Soft 300 Series Stainless Steel

  • Non-Magnetic

  • Misaligned Shafting: Problematic

  • Moment Loading: Problematic -
    particularly in Z axis ( vertical operation)

  • Failure Mode: Mild - increased running clearance due to wear - no loss of mechanical components

  • Chemical Resistance:
    EXCELLENT
